Leviton Toggle Slide LED Advanced Dimmer TSL01-W, White — 150W LED/CFL, Flicker-Reduction & Adjustable Range

Leviton's Toggle Slide LED Advanced Dimmer (TSL01-W) is a compact, single-pole/3-way dimmer that provides smooth full-range dimming for up to 150W of dimmable LED/CFL and full power for halogen and incandescent bulbs.

This slim white toggle-slide dimmer blends straightforward operation with versatile compatibility to update standard switches without rewiring. It uses a dedicated on/off toggle combined with a slide control for precise brightness adjustments, restores the last setting when switched back on, and fits into standard wall boxes—making it a practical retrofit for living rooms, bedrooms, hallways, and other common spaces.

How does the TSL01-W deliver reliable dimming with modern LED bulbs?

The TSL01-W is engineered to work with dimmable LED and CFL technologies, minimizing flicker while allowing smooth, stable light changes across the full dimming range. It includes trim adjustments so you can set the lowest and highest brightness to avoid lamp instability at extreme settings.

• Rated for up to 150W of dimmable LED/CFL load.
• Flicker-reduction design for consistent LED performance.
• Adjustable minimum and maximum levels to match specific bulbs.
• Full-range slide action for fine-tuned light control.

Can I use this dimmer in a multi-location (3-way or 4-way) setup?

Yes — the toggle-slide dimmer supports single-pole and common 3-way wiring. When paired with compatible 3-way or 4-way switches (sold separately), it lets you control lighting from multiple locations such as stairwells or large rooms.

What installation considerations should I know before buying?

Installation is straightforward: the device fits into standard wall boxes and does not require a neutral wire, simplifying retrofits in older homes. Its ultra-slim profile and standard toggle footprint make it an easy swap for a typical single-pole switch.

• No neutral wire required—reduces wiring complexity.
• Ultra-slim form factor fits most standard wall boxes.
• Dedicated on/off toggle retains prior brightness setting when turned off.
• Toggle wallplate sold separately for a finished look.

How can I customize lighting behavior for different rooms?

The dimmer lets you tailor fade rates and brightness endpoints so the same switch can suit a living room, bedroom, or dining area. Use the slide for precise daytime lighting, and dial down the minimum level for comfortable evening ambiance.

• Fine-tune minimum and maximum brightness limits.
• Adjustable fade-on rate for softer light transitions.
• Dedicated toggle preserves preferred levels between uses.
• Works with a wide variety of dimmable lamp types for consistent results.
